Fifty years ago, on April 22, 1970, people around the world marked the first Earth Day. Thousands gathered to raise awareness about the importance of protecting our beautiful planet for future generations. On this Earth Day, as we physically separate ourselves by necessity, we can still collectively appreciate the wondrous beauty of our planet and the extraordinary science that helps us understand how it all works – and we can do it from our homes. Much as our Earth’s systems are interconnected so, too, are all of us. To help connect us virtually this Earth Day, we encourage you to share on social media photos and images of how you marked the 50th anniversary, using the hashtag #EarthDayAtHome. This could be a picture of a special science activity, an original work of art you created, the tree outside your window, or whatever inspires you.
